Isidor is a male given name of Greek origin, derived from the Greek word 'isidorus', which means 'gift of Isis'. Isis was an ancient Egyptian goddess known for her magical skills and fertility. The name Isidor has been used throughout history, with notable bearers including Saint Isidore of Seville, a 7th-century Spanish scholar who is considered one of the most important intellectual figures of early medieval Europe. In various cultures, the name Isidor has been adapted into different forms, such as Isidor in German and Ysidro in Spanish. However, it remains relatively uncommon today, contributing to its unique and distinctive sound.
"Isidor saw its peak popularity during World War I, with 24 births both in 1914 and 1915. However, it has since declined significantly, with only 5 births recorded in 2018 and 14 in 2023."
